Side return extension steels in the West Midlands: how it works
Side return extension steels are the beams and columns that replace the side wall of a terraced house's rear wing when the narrow passage beside it is built over. Sized by a structural engineer, they carry the wall, floor and roof loads above along the line of the old wall, so the kitchen and the infilled side return become one wide room.
We carry out side return extension steels throughout the West Midlands, for homeowners, landlords and builders who need the structural part done properly. Coverage takes in Birmingham, Halesowen and Solihull and everywhere in between. You get an itemised written quote that shows the calculations, approvals, steel, labour and finishing as separate lines.
What to expect
- Where the beam along the old side wall meets a beam across the main house, the junction carries a heavy point load. The engineer usually details a column or a bolted connection there, which needs a solid foundation beneath it.
- Propping a side return is awkward because space in a narrow kitchen is tight and the infill side is often open ground. Props outside may stand on temporary pads or boards, set so they do not sink or shift in wet weather.
- Many outrigger kitchens have a chimney breast on the side wall being removed or on the party wall. Its position affects where beams can bear, and if any part of the breast is taken out, what remains above has to be supported as the engineer specifies.
- The side wall of a typical outrigger carries the first-floor wall above it, and sometimes the rear wing's roof and the joists of the room over the kitchen. That is why taking it out calls for a beam along its full length.
- Some owners leave the long beam on show as a feature under a glazed roof. Exposed steel still needs fire protection where building control requires it, which usually means a specified intumescent paint system applied to the correct thickness.
From survey to sign-off in the West Midlands
Free visit
A short visit to the West Midlands to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
Building control
We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
Steel in, made good
On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.
What do side return extension steels cost in the West Midlands?
As a guide, budget £3,500–£8,500 including VAT for side return extension steelwork in the West Midlands, based on published UK cost guides adjusted for prices in the West Midlands (no adjustment).
| Job | Typical guide range | What it usually covers |
|---|---|---|
| Side return extension steelwork | £3,500–£8,500 | Beams and posts along the old side wall line, propping and approvals (extension build extra) |
| Steel column or post | £500–£1,500 per column | Column supplied and fitted with base and cap plates on a pad foundation |
| Fire protection to a steel beam | £150–£600 per beam | Fire-rated board boxing or an intumescent coating system as specified |
| Opening into a rear extension | £2,500–£7,000 | Original rear wall removed with a beam or goalpost, approvals and propping, coordinated with the extension build |
Figures include our approximate regional adjustment for prices in the West Midlands (no adjustment) and are rounded. How these figures are worked out.
Building rules for the West Midlands
In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either the local council's building control team or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.
Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.
Questions about side return extension steels in the West Midlands
Which towns in the West Midlands do you cover?
We cover towns including Birmingham, Coventry, Wolverhampton and Dudley, plus the villages and smaller towns around them.
What happens at the survey visit in the West Midlands?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
Can a side return be built over a drain?
Sometimes, but drains in side passages need checking early. A shared or public sewer may need the water company's agreement before building over or close to it, and column foundations may have to avoid the pipe run. Manholes may need moving or adapting as part of the wider build.
Why does a side return need columns?
Columns are used where two beams meet or where there is not enough solid wall to carry the end of a beam. The column takes the concentrated load down to a pad foundation in the ground. Sometimes it can be hidden in a wall nib or boxed in neatly.
Can the outrigger wall be removed without affecting the bathroom above?
Yes, when it is properly propped and replaced with steel designed for the load. The floor and wall above are supported throughout, and the bathroom stays usable in most cases. Waste pipes or soil stacks on the wall being removed are rerouted first so nothing is disturbed when it comes down.
Does a glazed roof affect the steel beam?
Yes. Glazed roofs need the beam they sit on to stay very straight under load, so the engineer may set a stricter deflection limit than for a solid roof. That can mean a deeper or heavier steel section, and the roof supplier's details need sharing early.
How soon can side return extension steels start in the West Midlands?
Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
